Question

The sun produces 3.8x10^27 joules of energy per second. How much energy is produced in a year? (Note: a year is approximately 31,000,000 seconds.) Put it in scientific form.

Answer 1

If you're talking about the 'scientific notation', the answer would be (3.800000000000000000000000000, 26 zeroes.) 

Answer 2

Answer: About
`\approx1.178*10^(35)`

Explanation:

Given : The sun produces
`3.8*10^27` joules of energy per second.

It is also given that a year is approximately 31,000,000 seconds.

In scientific notation , it can be written as
`3.1*10^7`

Then , the amount of energy is produced in a year will be :-

`3.8*10^(27)*3.1**10^7\\\\=3.8*3.1*10^(27)*10^7\\\\=11.78*10^(27+7)\\\\=11.78*10^(34)=1.178*10^(35)`

Hence, the amount of energy is produced in a year
`\approx1.178*10^(35)`
